Vai@ B.HfoLMEsMncHrN-v L11-The numeral l13 represents aY horizontal yisoclrshaft which is arranged transversely `in-f'rontQoithe harrelisu'pportand j ournaled in'ghearings 111 on the front ypart of themain V jira-'meor hase. On 'opposite sides of the bar- V.rel support Varearranged twollongitudinal `lifting arms` 15, each o`f which is' mounted loosely atits-.frontend on the'rock shaft 1 3 .adjacent to` the-outerside of oneofthebear-V -ings14sothat this lifting armV turns about the samexaxis asthe shaftbut the arm 15 is capable of turning` with the shaft 13 kandthe shaft and arm are` also capable of turni'ingindependently of eachother.- ntlie rear of the lifting arms and arrangedon transverselyopposite sides of the barrelfsupport are two upright gripperarms 16 eachof whichis pivotally connected at itslower end i with the rear end ofone ofthe lifting arms by `means of a pivotppin, screw orv bolt 117arranged horizontally and lengthwisegrelatively tothe machine andpassing through the` lower part of 'the respectivegripper arm v"and intothe rear end' of the companion` lift-- ing/arm 15. .Y page with-one sideoi." thebarrel for pivoty-Upon the upper endsofvhe two gripper armsr arearranged two` jaws or chucks,

which are` adapted to engage with diametri-- cally opposite sides of thebilge portion ofV the Abarrel in a directiontransversely of themachine'. 4Each of these jaws comprises a head-18 which is adaptedtoerig/age with a part ofthe barrel vloodyand*whichis pivot-`allyconnected With-the rearend of one of :the adjusting'rods 23, insuch'inanner that f the head is eapable of swiveling on vthis rodsuccessively applied to ythese ends bythe :midwthus'` adaptitself t'ovvaryingfangular positions of the surface ot the barrel relative to thisrod. The first construction of the front face oi" the supporting headisconstructed in the form of a rubber pad 19 which is connected with thehead by means oi an under-cut boss arranged on the iront side of thehead and engaging with an under-cut recess 51 on the backof the pad, thelatter being provided on its front side with a plurality ot projections52 in order to enable the same to obtain a firm frictional grip on theside ofthe barrel. The pivotal connection between the gripper head andthe rod 23 is preferably effected by providing the rear side of the headwith a recess having reduced innerI part 53 which terminates in a "ballrace 54 and an enlarged outer part 55. cent rod 23 projects-into thisrecess oi the gripper head and is provided at its inner end with a ballrace 56 between which and the ball race 454 on the bottom ot this recessan annular row of balls 57 is arranged, while that part of'this rodwithin the enlarged part of the recess is spaced therefromcircumferentially. By means of this construction the gripper head isjournaled on the gripper rod 23 so as to rot-ate freely thereon andpermit the barrel to be easily reversed while at the same time thegripper head is free to rock or swivel in all directions and thus adaptthe face of this gripper head to the varying positions which the surfaceot the barrel may occupy relative to the rod 23. In order to prevent thegripper head from being moved lengthwise from the rod 23 and stillpermit of free rotation and swiveling motion ot head on this rod aconnection is provided between these parts which preferably consists ofthe cotter pinV 5 8 passing transversely through the gripper head andengaging with an annular groove 59 on the peripheryof the rod 23 in rcarof the ball race 56 thereof.

Means are provided for adjustingly mounting each ot these jaws on theupper part of one of the gripper arms so as to adapt these jaws tobarrels of different width and diameter. The preferred means for thispurpose which are shown in the drawings comprise a bracket 2O engagingwith the rear side of the upper part ot' each gripper arm and providedwith a horizontal transverse sleeve 21 on a separate part and a verticalslit 22 in its lowerpart eX- tending from the under side ot the bore ofsaid sleeve to the lower end of said bracket, the horizontal transverseadjusting rod 23 arranged in the sleeve 21 and carrying at its inner endthe head 18 of one of the jaws and a clamping bolt 24 passing throughthe lower split parts of the bracketand through an upright slot 25 inthe upper part of the respective gripper arm, as best shown in Figs. 4and 5. Upon loosening the clamp- The front lpart of the adjain the slot25, the gripper jaw can be raised or lowered to suit the height orlength of the barrel which is being coopered and by tightening theclamping bolt 24 the split parts of the bracket are closedor drawntogether so as toA grip the adjusting rod 23 in the sleeve 21 and at thesame time this bracket is drawnv tightly against the rear side ot therespective gripper arm, thereby holding the parts'in their adjustedpositions.

The downward movement of the lifting arms and the parts mounted thereonis eftected by gravity but if desired this may be aided by springpressure, as for example by4 preferably effected by the following means.

The numeral 29 represents lugs projecting laterally rinward yfrom thelower parts of the gripper arms and each having its inner partoverhanging the adjacent part of the base and provided on its undersidewith a downwardly open pocket 30. vWithin the pocket of each lug 29 isarranged a buffer spring 31 which engages its upper end with the bottomof this Y pocket. Extending downwardly through the bottom of this lugand the spring therein is a buiier rod 32 which has a shoulder 33 at itsupper end adapted to bear against the upper side of the lug 2S) whileits lower Aend is adapted to bear against the adjacent part of the baseand is provided with a shoulder 34 engaging with the lower endet thebuffer spring 31. These shoulders are preferably formed on this rod `byconstructing the same in the form of a bolt, the head of which forms theupper shoulder 33 and the nut of which forms the lower shoulder 34. Uponmoving each of the gripper arms downwardly the adjusting rod or member32 strikes the top of the base so that its further movement .in thisdirection is arrested, thereby causing the gripper arm during itscontinued vdownward movement with the companion lifting arm to be swungroutwardly at its upper end and thereby disengage the jaw or gripper onthis gripper arm from the periphery of the barrel. This releasedposition ofthe grippers or jaws fiom the barrel is indicated by fulllines in Figs. 1, 3 and 41j j y For the purpose of moving the upper endsof the gripper arms inwardly andengaging the jawsthereof withvoppos'itesides o ffthe barrel so that the latterv is gripped thereby.V

means are provided whichV in their preferred form are constructed: asfollows:

The numerals 35 'are two vertieally swinging shifting arms whichare-secured at' their front ends to the rook shaft 13'adjacent to theouter sides of the lhubs of the vlifting levers l5 'and each rovided atitsI rear end with a tappet 36 wlhichpreferably has the form of a`roller pivoted on the extremity of the respective shifting arm inanylsuitable manner. y Each of these tappets engage with a cam face 37which is formed on the lower `part of the ou-teredge of each gripperarm. At the 'lower andV upper "extremities of thek y cam face 87 ofeachgripper arm the latter is provided with lowerl and upper stops 38, 39,which limit the vertiealmotion of therespeetive tappet which co-operateswith this cam. On one part of the rock shaft 13, preferably the righthand end thereof, the same is provided with a forwardly projectingtreadle 40 on which the operator of the swingingmovement of each gripper:arm

machine is adapted to'step. The `outward away from the side of thebarrel is limited by engagement of a stop 41 arranged on the gripperjawsaredisengaged from opposite sides of fthe barrel, the shifting arms arelowered' and their tappets are in engagement with the lowermost parts ofthe cam faces 37 and the pedal 40 is in" its elevated position,

as shown in Figsl and 4.

Afterthe attendantlhas placed `a barrel in its operative position inwhich one of its ends engageswith the top of the 'table or platform l1the heading-up vmachine isiirst operated for applying a head to theiupper end of! thebarrel.` Thereafter: lthe operator steps on thetreadle 40 preliminary to Veffecting a reversal ofthe barrel endforrendj During the rst part of this downward'motion of theA treadle 40the shifting arms Vare raised and their tappets'l` are oause'd to moveupwardly alongthe cain -`faees 37 of the gripper arms whereby the4latter are moved inwardly forV toward each ,otherf and "the grippers orjawsthei'eon are caused 'to engage withop osite sides of thecentral'r'or 1 bilge portion o lthe barrel body. vAlfter the gripper"arms have .been vmoved inward-ly to fsuch an extent during the firstpart .of the downward movementof the treadle: as will` produire a. firmengagement ofthe jaws'with Y' thev opposite sides of the barrel then theconi` ftinued downward movement of the treadle i will fcausethe`shifting arms r`to produce 'a lifting'eifectupon the gripper arms andlifting' arms whereby Vthe barrel will` be i, lifted with its loweredend out of engage-f,V

ment fromy the top of the supporting table. or platform 11.` The raisingof the barrel at jthis time is only sufficient lto lpermit;y the lbarrelto be turned by the operatorabout 'the horizont-al transverse axisof the rubber pad l9whieh is'arranged axially in line` for this purpose.A. partial turning end for end of the barrel by the operatorisrepresented in Fig. 2 and when, this turning has been vcompleted sothatthe end of the barrel which formerly was uppermost is nowlowermost,then'the attendant removes his foot `pressure from the t-readle *40 soasto allow thebarrel to descend by gravity together with the gripping andvelevating mechanism f associated therewith. 'The Ibarrel is arrest- `edinit-s downward movement and engages,

its lower end with the table or platform during the first part of thedownward mo tion of the lifting arms and shifting arms,

Aand'during the lastfpait ,olf the downward Tf-f motion ofthelifting'arms and the gripper YY1arms thebu'ffer mechanism on the gripper"armsen'gage with the top of the `base 'so that `the gripper arms atthis* time 4are caused to vturnen the lifting arms land move `theirjawsout-wardly out of engagement from op'- 'positesides ofthe barrel.This outer movementot the'l gripper arms relatively to the `barrefbodyand the descent ofthe lifting arms islimited'by engagement of thestops;4l `on the gripper arms with the stops 42 on the lifting arms, as shownin Fig. 4.

The `downward movement of the shifting arms islimitedfby engagement oftheir' tappets 36v with `the lower stops 38. 'In the eventthat the shaftV113 is rocked by .the depression ofthe `pedal/l0 when no barrelis'presenten the platform excessl inward throw and possible displacement ofthe gripper arms is prevented by engagement ofthe tapi pets 36 withthe'upper stops 39 of the gri )per arms.

wing to theA fact'that a single depresy sion of the treadle 4() of thismechanism will produce a gripping andi centering of the bai'- 1:5

reli as: well as Va lifting `effect of thersame fromthe platform the.barrel is very easilyA and quickly placedina position'i-nr which theoperator can quickly and `convenientl'yt'urn the'barrel end for end onvthe' rubber pad CII Cil

This barrel reversing mechanismis very rugged in construction and notlliable to get out of order under the severe usage to which the same islikely to be subjected while in use and it is very effective in itsoperation of raising and lowering the barrel to permit of such reversalwithout requiring more than ordinary manual effort for this purpose,thereby materially increasing the out-- put of the barrel making machinein connection with which the same is used.
